Salut!
The hypotenuse of a right triangle is the longest side of the triangle. It is also the side opposite the right angle.
If you have an isosceles triangle with a hypotenuse of 24 mm, you can find the length of the legs, which are the other two sides of the right triangle, using the Pythagorean theorem.
Since the triangle is isosceles, then both legs are the same length. Thus, we have the following equation:
$$x^2+x^2=24^2$$
So you can solve this equation to find x, the length of a leg.
I'll let you do the math. If you have any other questions, we are here! :)
